    Hey everyone, please help. I am about to rip my hair out.

    I have a 3GS with the old bootrom that was upgraded to iOS4. I have my SHSHs stored on Cydia going back to 3.1.

    I downgraded to 3.1.2 fine, and then used redsn0w to JB to custom 3.1.2. I then used pwnagetool to create a custom 4.0 FW and upgraded. I have done this 3 times now, and no matter what I do my iphone has no carrier logo and no service. When I go into the general settings of my phone, it doesnt even list my phone number. It was synced and backed up with iTunes just fine.

    What do I need to do? Do I need to install Ultrasn0w even tho Im on AT&T???

    I just created a new custom IPSW and tried again. Still shows my number is "unknown" in my phone properties. I dont understand.

    If you are on official carrier did you uncheck the activate phone button.

    That should only be checked if you are on unofficial carrier (as in unlock).

    dhlizard is correct in Pwnagetool double click on general when it comes to costumization and uncheck the "activate phone" section.

    I think you do need to install ultrasn0w to get service on your iphone.
    Having just uninstalled ultrasn0w, it lead to loss of service.
    Reinstalling returned the service (o2). It seems to be the fix to the problem

    dhlizard is correct. When you are building your IPSW and you are on an official carrier you need to uncheck the 'Activate' box.
